Specification of Letters Patent.

Patented Oct. 15, 1912.

Application filed June 5, 1911. Serial No. 631,307.

To all whom it may concern:

Be it known that I, WVILLIAM I'IALL, a citizen of the United States, anda resident of the borough of Brooklyn, city of New York, in the countyof Kings and State of New York, have invented certain new and usefulImprovements in Machines for lVrapping Pamphlets and Similar Articles,of which the following is a specification.

The invention consists in the novel construction, combination andarrangement of various devices, elements and parts, whereby the objectof my invention is attained, all as fully and specifically set forth inthis specification, and in the accompanying drawings which form a parthereof.

The invention relates more particularly to the type of wrapping machineset forth and described in U. S. Letters Patent No. 699,419, granted toEdward P. Sheldon on May (S, 1902, and consists more especially incertain improvements and modifications of the machine of the saidpatent, but my said invention is not limited to use with such or anysimilar machine, but is capable of use with various types of wrappingmachines, and it will be obvious that any such use and any modificationof the devices herein described which may be necessary to adapt same foruse with other machines is within the spirit and scope of my invention.

Before describing in detail the construction and operation of myinvention it may be well to state the general plan or mode of operationof a machine of the kind referred to, which is as follows: A singlepamphlet, magazine, newspaper or like article to be wrapped, is takeninto the machine by devices provided for that purpose, and is conductedto an approximately cylindrical wrapping space formed inside of andbounded by a series of rollers, which rollers progressively bend thearticle and form it into a cylindrical roll. Before the process ofrolling is completed the previously gummcd or pasted wrapper is led intothe wrapping space and rolled around the article, which is then ejectedfrom the wrapping space.

In the machine of the above mentioned Sheldon patent the ejection of therolled and wrapped article is accomplished by allowing the same to dropinto a peripheral groove in the lowest series of rollers, (which are ofsubstantially larger diameter than the other rollers bounding andforming the wrapping space) which groove carries the said wrapped androlled article around and away from the wrapping space and deposits itupon a traveling apron by which it is conducted ont of the machine.Prior to the said Sheldon patent wrapping machines were known in the artwhereby articles could be rolled and wrapped in a wrapping spacecomposed of a series of rolls and ejected endwisc from the wrappingspace, and also machines in which the rolled and wrapped articles wereejected sidewise between two adjacent rolls which at the proper timewere separated for the purpose, and it will be obvious that my presentinvention is adapted to be used in connection with machines of any ofthe said types as well as with machines of various other types.

. My present invention relates specifically to the devices for feedingthe articles to be rolled and wrapped into the wrapping space, all ashereinafter more particularly described.

In the accompanying drawings, Figure 1 is a side view of a portion ofthe machine, showing the pamphlet feeding devices and the wrapperfeeding, cutting, gumming and perforating devices; the wrapping devicesbeing indicated diagrammatically; Fig. 2 is a side view of a part of aportion of the pamphlet feeding devices, on a larger scale; Fig. 3 is atransverse section, looking back from the front end of the machine,taken on the line 3 3, of Figs. 1 and 2; Figs. 4L, 5 and 5 are detailviews showing portions of such mechanism, taken from the other side ofthe machine from that shown in Figs. 1, 2, &c. and Fig. (3 is alongitudinal vertical section of the pamphlet feeding mechanism, all ashereinafter more particularly described.

Referring now to said drawings, it will be seen that side frames 12 areprovided, in which are journaled the various shafts, and by which otherportions of the machine are supported. These frames may be of anysuitable form and shape. At the front of the machine, being at the rightin the side elevations and plan views of the drawings, the pamphletfeeding mechanism is located, and toward the rear the wrapper mechanism.

At the front end of the machine (see Figs. 1 and 2) a platform 13 issuitably supported upon brackets 12, and upon this platform thepamphlets to be wrapped are laid flat, preferably with their backs orbound edges toward the machine. Several of these pamphlets are shown at14 in Fig. 2. They are placed with their back edges against the uprightguides 15, which are secured to the bar 16, which is supported by thebrackets 12 and are held in this position by the adjustable stops 17,which bear against the outer or front edges of the pamphlets and keepthem pressed backward, their back edges projecting a short distancebeyond the back edge of the platform 13, being thus free of its support,and abutting against the segmental reciprocating roller 18 and feedingwheels 19 as hereinafter described.

Upon one of the main driving shafts of the machine, 31, (see Fig. 1) isa bevel gear wheel 32, which engages with another bevel gear wheel 33 onone end of a shaft 34. On the other end of this shaft 34 is anotherbevel gear wheel 35 which engages with a similar wheel 36 on the shaft38. On this shaft 38 is a larger plain gear wheel 37, (see also Fig. 2)which engages with the gear 26 (see Fig. This gear 26 is rigidlyconnected, by the neck 42, (see Fig. 3) to the gear 24, which engageswith the gear 25 on the shaft 21 (see Figs. 2 and 3). From the gear 26extends laterally the interior core or shaft 27 (Fig. which bears thefeeding wheels 19 rigidly secured thereto and revoluble therewith, andwhich also bears the sleeves 18, loose on said shaft 27, andintermediate and also exterior laterally to the wheels 19. From the gear25 there extends laterally the shaft 21, which also bears feeding wheels20, located just below and in contact with the feeding wheels 19.

The sleeves 18 are connected together by the bar 22. The sleeves 18 donot revolve, but are reciprocated, by means of the mechanism now to bedescribed, shown in Figs. 5 and 5", and which is located on the side ofthe machine opposite to that shown in Figs. 1 and 2.

On the shaft 38 is keyed a crank-arm 45, to which is pivot-allyconnected one end of a link 46, the other end of which is pivotallyconnected to a crank-arm 47, which is keyed to the adjacent sleeve 18.It will be obvious that the rotary motion of the shaft 38 thus producedcauses a reciprocating rotary motion of the three sleeves 18, which aresecured together by the bar 22. The stop 48 prevents too great amovement of the crankarm 47 To the bar 22 and the sleeves 18 are securedblocks 50. The pamphlets lie on the platform 13, pressed by the guides17 so that they lie fiat when the sleeves 18 are in such a position thatthe bar 22 and blocks 50 are below the back edge of the lowest pamphletin the pile. When the sleeves 18 are rotated and the bar 22 and blocks50 are carried upward, the lowest two or three pamphlets of the pilehave their edges pushed backward and thus buckle slightly between theedge of the platform 13 and the sleeves 18. The upward motion of the bar22 continues until the blocks 50 pass above the edge of the lowestpamphlet, whereupon the pamphlet straightens or flattens out, the edgepassing under the blocks. At this time the reciprocating motion of thesleeves 18 and the consequent upward motion of the bar and blocksceases, and the reverse or downward motion of the bar and blockscommences, and this movement bends the edge of the lowest pamphletdownward so that it passes between the feeding wheels 19 and 20 (Fig. 3)and is drawn into the machine and delivered on to the sloping platform41, down which it slides to the devices which feed it to the rolling andwrapping mechanism, which feeding devices are shown in Fig. 1 and at theleft in Fig. 2.

In order to prevent the whole pile of pamphlets from being elevated orbuckled as the bar 22 passes upward, I provide fingers 29, which pressupon the edges of the lower two or three of the pile of pamphlets. Thesefingers are set in the bar 30 and rigidly secured thereto. At the endsof this bar are similar fingers 28, which bear upon cams 51 on thesleeves 18 (see Fig. 4.) These fingers pass through and are supported bythe uprights 7 8, and they as well as the fingers 29 also move freely upand down through perforations in the bar 16. They are drawn downward bythe springs 52. These parts are shown in Fig. 3, and a portion thereofmore plainly and on a larger scale in Fig. 4. It will be understood thatthe bar 30 is supported in place by the engagement of the fingers 28 and29 with the uprights 78 and the bar 16.

The devices for feeding along the pamphlets will now be described. Onthe main driving shaft 31 is secured a small sprocket 60 (shown indotted lines in Fig. 2.) From this leads a sprocket-chain 61 to asimilar sprocket 62 on a shaft 69, which also bears a gear-wheel 63. Onthe shaft 31 is also a cam 65, which bears against a cam-roller 66 borneon a lever 67, suitably pivoted at 68. The roller 66 is kept inoperative contact with the cam 65 by a weight on the lever 67, or aspring operating thereon, or other suitable means. On the other end ofthe lever 67 is a gear-wheel 64, rigid on a shaft 70. On the shafts 69and 70 are feedingwheels, 63 and 64 respectively similar to thefeeding-wheels 19 and 20. It will be obvious that as the shaft 31 andits cam 65 rotate, the gears 63 and 64 will be intermittently throwninto engagement and will operate the feeding-wheels 63' and 64 on theirrespective shafts, and that these feeding-wheels will operate to drawthe pamphlet from the platform 41 down so that it will be placed inposition to be transferred into the rolling and wrapping mechanism. Theconstruction and operation of the rolling and wrapping devices aresubstantially the same as in the Sheldon patent heretofore referred toand are not claimed in this application and need not here be described,further than to say that the pamphlet is rolled and at the same time awrapper, which has been previously gummed, is placed around it andsecured thereon, and the wrapped pamphlet then ejected from the rollingand wrapping mechanism and delivered out of the machine.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is as follows:
